Almost certainly no one here will write the whole thing for you. Show us what you got so far, say concretely where you got stuck and we'll help you.
By the way, the specification of your function is quite lousy. It is not really clear what the input is; integers, an array of integers or maybe a string with integers? From your example it seams to be the latter. If so, do you want to sum up the digits or how should the function know where to break up the string into integers?

Well its only INTEGERS not array any intergers.
and yesterday i had this work interview and they asked me this question and it bothers me

i've tried, but i can't get it done! there is must be an array but how can i know how many digits are there without convert the input to string!

I'd say that the job isn't the right one for you. This question is a variation (at least on the same level) as FizzBuzz
For more information listen to this podcast[^] or read the transcript[^]
Anyone with a software development job should be able to do that in a couple of minutes

He knows that you're not able to programmatically solve this quite simple problem on your own. Since the interview question implies the job has something to do with programming, your obviously not the right/best choice for the job and the other way round.

Anyone who passed CS101 should be able to do this in 5 minutes with one hand tied behind their back. If you can't, you should give up your software aspirations and take up a new career as a burger flipper.

We may not know you, but we've certainly cleaned up enough messes left by people just like you. The question was basic stuff - it shouldn't have bothered you. Even if you didn't know the ins and outs of the language, you should have been able to come up with the algorithm for it without needing to think about it.
You should also have been able to explain the problem properly, without using txtspk.
Overall, I'll take one Colin over 100 of you any day.

Well thanks again for the reply. but you know you don't have to say such things if you can erase my account so do it!! but don't act like the YOU ARE THE BEST or i dont know wats the matter with u!!! i asked a question AND I DON'T KNOW THE ANSWER nth to be shamed of!!! and btw i`m a software engineer we didn't took PROGRAMMING LANGUAGES as u did !! we only took the software engineering syuff and rational rose!!
You dont even deserve my reply!!!
Good bye MR

By definition, a software engineer has to be able to break algorithms down. You couldn't. You're right, there's nothing to be ashamed of when you don't know the answer to a problem - unless that problem is basic. I would be interested to know how you think you are a software engineer if you didn't do any programming languages.
Colin pointed out to you that you may not be pursuing the right career. I pointed out to you why I thought he'd done so because you couldn't seem to grasp this. Your answer has compounded the issue. As a professional developer, I have spent a large amount of time mentoring and helping newbie developers but I would advise anybody who couldn't get a grasp on such a basic problem to steer clear of a career in developing. More importantly, as I stated earlier, I have spent a large amount of time clearing up after people who shouldn't have been developers in the first place. If you want to prove me wrong, brush up on your algorithms, learn the basics and then move onto more advanced things.

I Know the basics.. !!
int x= int.Parse(Input.Text);
int t =0;
string i = x.ToString();
for(int y=0;y<i.length;y++)
{
="" int="" sub="int.Parse(i.Substring(y,1));
" t="t+sub;
" }
="" output.text="t.ToString();
"
this="" is="" wat="" i="" did!!and="" its="" working,="" but="" im="" asking="" there="" anyway="" can="" do="" it="" without="" parse="" the="" to="" string?!="" so="" get="" length="" and="" substring="" functions.=""

that's quite a different question from the one you asked at the start 
Can i suggest not using the letter i to denote a string, even if it does contain the string representation of an integer.
You should use Parse or TryParse on the input to make sure that the number can be represented as a number.

So why didn't you show us the code and asked exactly that question in the first place? Why did you told us "i've tried, but i can't get it done!"?

bcuz i've tried and maybe my question wasn't so clear.. i was trying to tell u guys i want the answer without parsing the input into integers..
anyway i got the answer thanks for ur time

Certainly not.

You never even clearly stated that the input is the string representation of an integer. By the way, there is no way I can think of that wouldn't require you to do some parsing. You cannot do mathematical computations with strings.

private void Button1_Click(object sender, System.EventArgs e)
{
int x= int.Parse(Input.Text);
int sum = 0;
while (x > 0)
{
sum += x % 10;
x /= 10;
}
Output.Text=sum.ToString();
}
how about this one?

Computes the sum of the digits of the number entered in Input control, but I gues you already know that. What is the actual question here.
By the way, you should surround the Parse operation with a try-catch-block to catch the FormatException thrown when the Input control does not contain a valid string representation of an integer (or use TryParse when programming for Framework version > 1.1).

What kind of crazy Software Engineering course did you do? The university I went to offered SoftEng courses and they included C++ and COBOL (it was a while ago) in the curriculum.

COBOL - almost a good anagram.

try out
public void sumOfInt(int num)
{
int tot =0;
string nubstr = num.ToString();
for(int y=0;y < nubstr.Length; y++)
{
int sub = int.Parse(nubstr.Substring(y,1));
tot=tot+sub;
}
MessageBox.Show("Sum of Integers"+" "+tot.ToString());
}

Thanks buddy

Alternatively without using strings at all:
public int CrossSum(int value) {
int sum = 0;
while (value > 0) {
sum += value % 10;
value /= 10;
}
return sum;
}
Frankly, Estarta, if you are applying for a job as a programmer, you should be able to write something simple as this yourself.
